1.C
2.
a) Sulfate
b)Orthorombic
c)Uneven
d)3-3.5
e)brittle
1 and 2 are right. There is another one. Did you miss it, or are you doing it right now?
I will go away now. He he
Anyways, question 3 is sort of hard to write w/out giving away the mineral, so it's really ambiguous right now. If no one gets it you can just go ahead and make your question
EDIT: Okay, sorry I saw your answer after I posted that, sorry
Number 3 is right, sort of.
It's too soft (3 means it can be scratched with a coin), brittle, and hard to cut.
So I guess these are all cons.

I wanna say it's a limestone....probably wrong. Not sure the type.
Some limestones were formed by chemical deposition and others by the accumulation of shells from minute sea creatures.
